   OpenGL Buffer Cleanup Utilities
   ===============================

   This module provides helper functions for safely deleting OpenGL buffer objects,
   including vertex buffer objects (VBOs), vertex array objects (VAOs), and dictionaries
   of buffer handles. It ensures proper resource cleanup and avoids memory leaks in
   graphics applications.

   Dependencies:
   -------------
   - OpenGL (PyOpenGL)
   - picogl.backend.modern.core.vertex.base (for VertexBuffer type)

   Functions:
   ----------

   .. autofunction:: delete_dict_buffers
       Deletes all buffer handles stored in a dictionary and clears the dictionary.

   .. autofunction:: delete_buffer_object
       Deletes a buffer object if it is valid and has a non-zero handle.

   .. autofunction:: delete_buffer
       Deletes a raw buffer handle if it is valid.

   .. autofunction:: delete_vao
       Deletes a vertex array object (VAO) if it is valid.

   Usage Example:
   --------------

   .. code-block:: python

       delete_buffer_object(my_vertex_buffer)
       delete_vao(my_vao_id)
       delete_dict_buffers(buffer_map)
